Answer:
The term mechanical digestion refers to the physical breakdown of large pieces of food into smaller pieces which can be done by digestive enzymes, hydrochloric acid. Mechanical digestion in the stomach results in the formation of bolus.

The answer is <span>A) All future somatic cells of the organism will contain the (2n + 1) number of chromosomes.
An egg cell and a sperm cell fuse to develop a new organism in a process called a fertilization. As a result, a zygote is formed. When the </span>egg cell containing the (n+1) number of chromosomes combines with a sperm cell containing the (n) number of chromosomes, the zygote will have (n + n + 1), which is (2n + 1) number of chromosomes. The zygote is the first cell of the new organism. It undergoes mitosis resulting in somatic cells where all of them will contain the same <span>number of chromosomes as the zygote, which is (2n + 1)</span>

Explanation:
Hypophosphatemic rickets is a disorder characterized by hypophosphatemia (low level of phosphate in the blood), defective intestinal absorption of calcium, and rickets (impaired mineralization of cartilaginous growth plates) or osteomalacia (impaired mineralization of the osteoid) unresponsive to vitamin D. It can be inherited or acquired.
When it comes to inheritable hypophosphatemic rickets, the disorder is most often inherited in an X-linked dominant manner. This means that the gene is inherited through the X chromosome and that one dominant allele is enough to cause it.
As the mother is heterozygous for the trait, she has one dominant and one recessive allele (XHXh). The father has one X chromosome, which he inherited from his mother, and as he has the condition, the dominant allele will be present on it (XHY).
This means that, if the child is a girl, she will definitely have the disorder. Girls inherit one X chromosome from each of their parents. Even if she inherited the one with the recessive allele from her mother, she would get the one with the dominant allele from her father.
If the child is a boy, he has a 50% chance to inherit the condition. Boys inherit the Y chromosome from their father and the X chromosome from their mother. As the mother is heterozygous, he can either get the chromosome without the dominant allele or the one with it. This means that there is a 50% chance of inheriting the disorder.
If we say that there are equal chances of this couple having female and male children, when we combine these results, we get a 75% chance of them inheriting hypophosphatemic rickets.
